SCSI-1 allows asynchronous data transfer rates of 1.5 Mbps and synchronous transfer rates up to 5 Mbps. It has an 8-bit SCSI port that uses a 50-pin connector and single-ended, open-collector drives. SCSI-1, the original SCSI standard, became obsolete with the development of SCSI-2.

SCSI-3 allows for faster data transfer rates and the use of up to 32 devices on a single chain. It incorporates serial connections in addition to the traditional parallel interconnect of SCSI-2. The serial interconnect of SCSI-3 incorporates three technologies: serial storage architecture (SSA), Fibre Channel, and IEEE P1394. The serial transfer mode allows faster data rates, more devices per bus, simple connectors, and longer cables.

BNC connectors are very secure bayonet-style locking connectors that are used in broadcasting gear for both video and radio signals. It is also common on professional test equipment. In consumer audio/video, BNC connectors are used mostly in high-def. set-top receivers and high-end video monitors, often as RGB or component video inputs. This connector is used on older monitors, frame buffers, and accelerators. Many third party monitors also have this connector.

DB25 is a 25-pin used for both serial and parallel ports on computers. Sometimes, DB25 is used for controlling audio gear by computer or on THX gear, to connect multiple audio channels with one cable. DB25 is also used in custom installations where numerous cables must be bundled. It’s used for some RS232 and RS423 serial connections. Finally, DB25 is also used for the parallel connection on IBM printers.

DVI-I connectors are integrated products that transmit both analog and digital data. Some video cards use this connector type so that either a DVI digital screen or analog VGA monitor can be connected.

USB Type A connectors has a flat, rectangular interface. They provide 5 VDC power on one of the pins and are designed for connections with host controllers and hubs. USB cables with Type A adapters on both ends are not designed for direct connections between computers, or between a PC and a USB hub. Rather, A-A cables should be used to connect USB devices with an A-style female port to a PC or another USB device.

USB Mini-B connectors are miniaturized Type B connectors that are 3 mm x 7 mm in size. They are available in 4-pin and 5-pin versions. The USB On-The-Go standard specifies the use of 5-pin USB Mini-B connectors to allow peripheral devices to communicate with a host controller. The 4-pin is unofficial, but used with many digital cameras.

USB Micro-A connectors are white, 5-pin devices. They are used mainly with newer mobile devices. Micro-A connectors are smaller than Micro-B connectors, but still support high-speed data transfers of 480 Mbit/s and USB On-The-Go technology.

Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl and polybrominated diphenyl ether. RoHS will become effective on July 1, 2006.

Products that bear a CSA Mark have been tested by the Canadian Standards Association (CSA) and meet applicable standards for safety and/or performance. These standards are written and administered by organizations such as the American National Standards Institute (ANSI), Underwriters Laboratories (UL), and CSA International. CSA Marks may appear alone or with indicators. CSA Marks that appear alone are used with products certified primarily for the Canadian market, to the applicable Canadian standards. CSA Marks that appear with the indicators “C” and “US” or “NRTL/C” is used with products certified for both the U.S. and Canadian markets, to the applicable U.S. and Canadian standards.

CE Marking indicates that a product complies with the essential requirements of relevant European Union (EU) directives that uphold national standards for health, safety, and environmental protection. CE Marking is required in the countries of the European Economic Area (EEA), an organization that consists of the twenty five member states of the EU and the three members of the European Free Trade Association (EFTA). CE Marking refers to the safety of a product. It is not a quality standard.

The International Standards Organization (ISO) is a worldwide federation of national standards organizations from over 100 countries. ISO's mission is to facilitate the international exchange of goods and services, and to foster cooperation in the spheres of intellectual, technological, and economic activity. ISO certifications include ISO 7779, ISO 9000, ISO 9001:1987, ISO 13485, ISO/TS 16949:2002, ISO 14000 and ISO 17025. ISO 7779 is concerned with acoustics, telecommunications equipment, and the measurement of airborne noise emitted by information technology (IT) equipment. ISO 9001:2000 establishes requirements for company quality management systems. ISO 13485 is concerned with medical devices, quality management systems and requirements for regulatory purposes. ISO 14000 establishes requirements for environmental management policies that minimize a company’s harmful effects on the environment. ISO 17025 outlines the general requirements for the competence of testing and calibration laboratories.

The International Electrotechnical Commission (IEC) is a global, non-profit organization that develops and maintains voluntary quality, safety, and performance standards for electrical materials, products, and systems The IEC also publishes standards for the electronics and telecommunications industries. The IEC’s membership consists of the electrotechnical standards organizations from each of its 51 member nations. The American National Standards Institute (ANSI) represents the United States.

Under rules and regulations, Title 47, Part 15 Subpart B, the Federal Communications Commission (FCC) regulates all commercial electronic devices (unintentional radio-frequency radiators) destined for sale in the United States that have clocks / oscillators that operate at a frequency greater than 9 kHz and that use digital techniques. This includes most products that employ microprocessors, as well as RF devices.

UL Recognized Component Marks are used only on component parts that are part of a larger product or system. These components may have restrictions on their performance or may be incomplete in construction. Products intended for Canada carry the Recognized Component Mark "C."

Verband Deutscher Elektrotechniker (VDE), the Association of German Electrical Engineers, is a non-profit testing institute that publishes standards and certifies electrical and electronic components. The VDE Mark indicates conformity with VDE, European Union (EU), and internationally harmonized standards. It confirms compliance with the protective requirements of the applicable EU directives.

The characteristic impedance of a uniform line is the ratio of an applied potential difference to the resultant current at the point where the potential difference is applied, when the line is of infinite length. Note that the term impedance is applied only to a uniform line, of which coaxial cable is an example. There are three main impedance groups in coaxial cable: 50, 70, and 93 ohms.
